FRANK E. SAGENDORPH, OF PHIL-DELPSA, PENNSYLVANIA.

Applicationlled Mey 10, 1909. Serial No. 495,204.

To all whom may camera:

lle it known that I, FRAM; E. SAGEN- noarn, a citizen ot' the llnited States, residing' in Philadelliihia. Pennsylvania. have invented on'tain lniproveinents in Farringllt'rips. ot which the following' is a specilieation.

Une object oi my invention is to provide a iurring' strip especially designed for ase with metallic ceiling' and Wall plates? whereby'it shall loe made impossible for suoli a degree of heat to be transmitted troni the ceiling' plate to a ioist or other combustible structure as would be sntlioient to set tire to v the. saine; it being' further desired that the strip shall be so made as to able structural strength;

Another object of the invention vide thicknesses of nneoinlnistihle material. usupossess ConsideriS to proa t'urringsltrip ,in ivlgiehfa number of g all)T metal` shall be interposed between a. inel tallic ceiling'v plate and the structure to which it is fastened: the construction being siarh that said strips shall contain air spaces as 'well as ainain body portion.

'll'iese objects and Y other advantageous ends l secure as hereinafter set forth, rei erence being had to the aeoinpanying drawings, in whielum- Figure l, is a section illustrating my invention as applied t'or the support ot' metallie plates; 2 and 3, are perspective views illustrating the detail construction ol two slr'htlv ilillerent varieties of turring' strips; and. lligr. l? is a transverse vertieal section ol' that Atorni of Figs. l and 2.

,in applying' metallic plates to Walls or eeilingrs, it is customary to .tirst mount upon` the jois'ts or studding' aseries ot' pi'operlj)7 spaced Wooden terrine' strips and then nail auch plates` to then'x. ln nianv eases, hon'- ever. the lire underwriters have objected to or prohibited thisConstruction. since in the event ot' a lire the metal plates would qnioltlv transmit to the farting strips sufficient heatto ignite theni and so set tire to the joists orother strut-.tures .to which they were nttaehed. ln order to avoid this possibility` l envelop each lnrring' strip in a Wrapping: of sheet. metal, .overlapping the edges ot' the saine in sneh a nianner that a double lhiekness ol' metal is interposed either between the strip and the inist or between the. l"trip strip shown in addition, l preferably eorrnggate Wrapping. ln the i, it i) strips B are attached at suitable inte in an y desired manner. Each ot hes-e strios is provided. .vith a cover or wrapping C sheet nietal which. if des ed, may be loi tudinally corrugated as shovvn in or ti':ii1s\.fe1'sely corrugated as sho'svn at in Fig. rl`l1e dimensions et' this Wrapping or cover are such that one edge completely overlaps the other to a distance preferably equal to the Width ot lthe :Earring strip.) end in mounting saitl strips this donhle thickness ot' metan is interposed. between the hotly /f and the joist ift.

The metal ceiling or 'wall mounted on the strips in anv desired manner, and have vantageous to nail said plates strips E directly to the joist, in f fastening them directly to said n'i. strips. In any easeil; will he noted that @.0 there is at least one thickness' ot nietal hee. il

l tween the farting' strip and the metal plate and one or. preferably tvvo intimes-:ea ot'l inetal between the strip and the or studding, so that even the most. inf'ense heat applied to the outer surta :.1 o the nietal plates' .D @anais iest have no deleterious effect other thanto char the wooden i irl im or bodies I) of the farting' strips. ln :idilition to the aloove`v howeveul it 'will bev noted that the eorrngations ot the sheet nietal Covering provide air spaces between said covering and the Wooden body 5 and in andi tion said eoverii'ig tout-hes4 the had): over hat relativel)Y liniited areas. 'lhis` emislrnetion. therefore, further assists in preventing a dangerous deg-ree el" heat beingy transmitted to the bodies b ot the farting` strips. so that even the chances ot' their charting when er'- posed to intense heal' are grealljv` reduced.

l. The Combination ot a series o support-- ing' strnetnres, t'inringA strips mounted thereon, metal plates on the said strips'` eael. strip being' provided with a metallic Covering' ot' which at. leastthree lhli" lint-esos are inletposed between the plates and the sinportine' l tl (i 'etna-,tures lili:

ing, the ends of which overlap so as tov provide a double thickness of metal between said strip and the supporting structure.

ering, with metal plates mounted on saidv strips.

4. As a new article of manufacture, a

fuifring strip consisting of a supporting body and a metallic coveringtherefor, the edges i l I @aegee of said covering being overlapped to provide a double thickness of metal over one side ot' said body.

l'n testimony whereof, have signed my name 'to this speciczition7 in the presence of two subscribing Witnesses.
